FreeBSD : irssi -- multiple vulnerabilities (85e2c7eb-b74b-11e7-8546-5cf3fcfdd1f1)

high Nessus Plugin ID 104062

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Irssi reports :

When installing themes with unterminated colour formatting sequences, Irssi may access data beyond the end of the string.

While waiting for the channel synchronisation, Irssi may incorrectly fail to remove destroyed channels from the query list, resulting in use after free conditions when updating the state later on.

Certain incorrectly formatted DCC CTCP messages could cause NULL pointer dereference.

Overlong nicks or targets may result in a NULL pointer dereference while splitting the message.

In certain cases Irssi may fail to verify that a Safe channel ID is long enough, causing reads beyond the end of the string.

Solution

Update the affected package.
